How to clean your central air conditioner drain tube

ac drain tube, condensate drain, john c flood, central air conditionerAny home that has a central air conditioner unit installed has a condensate drain line.  Air conditioning units produce one natural by-product, Water!  The warmer air from your home, meets the colder surface of the evaporator coil and naturally, condensation occurs.  The water from your AC unit runs down the sides of the coil and collects inside the condensate pan, eventually reaching the condensate drain and flowing off to the drain method your installer chose during installation.  If the drain line becomes clogged, there is no place for the excess water to go. This leaves your home opened to water damage.  

There can be a variety of drain set ups depending on the size, set-up and location of your central A/C system, so you will need to locate the drain on your system.

Regular care and maintenance of your air conditioning unit are important to keep it operating properly.  A/C drain tubes should be cleaned once a year to keep it free of algae and clogs.

We have produced a do-it-yourself video showing you how to clean you’re A/C drain tube.  Click Here to view the video.

I have regular service maintenance done,so usually don't do it myself.

Everything I've seen and heard so far says to use bleach to clean an AC drain line. Is there an alternative product that can be used? I am allergic to bleach and can't use it anywhere in my home.

From what I have heard you can also use white vinegar as an alternative to bleach. Some online articles say that white vinegar is actually preferred to bleach because bleach can damage your drain line - especially if you drain line is PVC or ABS plastic.

Please look at this alternate way of removing clogs within seconds from inside the safety or your home using compressed air power like a simple bicycle pump. It installs in 5 minutes, is already and their is NO cleanup. Since there aren't any wholesale/middlemen? or stores the cost is direct to the public. The cost is just $18.88, and even a clear "water flow view" tube is also available. The Deluxe unit has the ability of DIRECT access to the full drain line, and allows the removal of the top for adding cleaning solutions as a preventive, and/or also allowing the hook up of direct attachment to a expandable hose to power flush the ENTIRE line. It's patent pending. All the video and animations are shown on the website.www.acdraincleaner.com. We'd love your feedback. Thank You Again Elliot Berman 954-655-0059 (We also make a model that is sold exclusively to air conditioner contractors. Everything screws on to avoid any leaks, and therefore no holding force is even needed.)

I understand vinegar is good for semiannual flush of drain line.
